Matt, Thanks for your work on this.
I've had a little play & it looks ideal for my purpose & you should see an improvement in the BR8 area as a direct result. If your not doing it already, could you put somewhere on the front page when the data was updated. My initial plan is to have one session a month correcting & adding postcodes, but you may get other views.

As such I've now got working (to a state I'm happy with) a sub-website on my Postcode Finder to provide an interface to that data. Currently running at http://milliams.dev.openstreetmap.org/postcodefinder/landregistry/ (there's no public link to it yet so you'll have to bookmark it) it does the following: Given a postcode (or postcode fragment) it finds all the houses in the Land Registry database and tries to match each of them up to an address in my Postcode Finder database. If it finds a match it classifies it into one of three classes: - The postcode matches between OSM and the Land Registry - The postcode doesn't match - There's no postcode If you perform a search (like http://milliams.dev.openstreetmap.org/postcodefinder/landregistry/search/?postcode=CV4+8) you see that I've sorted the classes by 'importance' order so wrong postcodes are first, followed by missing postcodes. Then the ones that couldn't be matched to any address and finally the perfect matches. Give it a try yourself. It should be able to handle anything from "CV4" level (will take around 10 seconds to load (probably more for big cities like Birmingham and London) down to "CV4 8DU". It will almost certainly struggle if you try to put in "B" or something big like that. If you want to search for all the "B1" postcodes but exclude "B10", "B11" etc (since that would be a very slow query) then just put a space after it in the search box ("B1 ") or a plus in the URL ("?postcode=B1+"). It's probably best to only give it as specific a postcode as is possible ("XXN N" is quite quick) to keep the load low on the dev server. There's still some things I want to do with it but it's now in a workable state. The data from the OSM database is a few days old now. I'll wait for Geofabrik's ODbL extracts to be released before I update again. It should also be possible for me to extend the service to include and data source which contains "house number; street name; postcode" so I'll look into that in the future. -- Matt Williams http://milliams.com _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
